2.3.18 Clear CMOS jumper block (JP19)
To reset the RTC (Real Time Clock) CMOS data, you need to change the jumper cap of JP19 from
1-2 close to 2-3 close, then set to 1-2 close again. After that, you should get into BIOS setup
program and choose LOAD SETUP DEFAULTS, then you will now get original manufacturer
default setting in your CMOS.
2.3.19 System Hardware Monitor
The system hardware monitor supports following features:
Temperature sensor to monitor system temperature
Voltage sense monitoring to detect voltage level (+12 V, -12 V, +5 V, -5 V, +3.3 V)
Fan speed sensors for up to three fans
With a proprietary application, the system hardware monitor logic will check the voltage,
temperature and fan speed all the time. If any failure occurs, the application will prompt warning
message in a real time.
2.3.20 SCSI Subsystem (SCSI, SCSI_WIDE and JP20)
The onboard SCSI subsystem features the Adaptec AIC-7880, which is an Ultra Wide SCSI
controller and a PCI bus master interface. It provides up to 40 MB/sec throughput per channel.
The motherboard has two SCSI connectors: one high-density 68-pin Wide connector and one
50-pin Narrow connector.
Use the onboard 68-pin connector for cabling to 16-bit Wide SCSI devices and use the 50-pin
connector for cabling to 8-bit narrow devices. From end to end, a SCSI cable is route, in a daisy
chain fashion, from the last internal SCSI device to each subsequent internal device including the
onboard host controller. The cable can then connect to an optional converter card (External Kit)
installed in an unused I/O slot of the chassis. From the external kit, an external SCSI cable can be
used to connect external SCSI devices.
For proper operation of Ultra / Ultra Wide SCSI devices, the overall length of the SCSI cable
from the last internal device to the last external device should not exceed 3 meters with four Ultra
/ Ultra Wide SCSI devices and 1.5 meters with eight peripherals per channel.
Install or enable terminators on the last physical SCSI device at each end of the SCSI bus (Note
that a SCSI bus can comprise several SCSI cables) and remove or disable terminators on all other
devices on the SCSI bus. The motherboard will set its terminator to proper state automatically.
Make sure you have assigned each device on the SCSI bus, including the onboard SCSI controller,
a unique SCSI ID.
